Light Brigade offers DVD for fiber-optic safety training
The Light Brigade, the training division of AFL, has released a new menu-based staff development DVD, titled Fiber Optic Safety. This DVD is designed to inform anyone who works with optical fibers or lasers, or who installs or operates fiber-optic communication systems, about fiber safety.The DVD's 10 menu-selectable chapters focus on several topics, including: Laser types and lassifications, how they operate, and various control measures National and international fiber-optic and laser safety standards Optical fiber handling and safety Chemicals and right-to-know documentation Fiber and laser testing and inspection equipment types and lications The impact of high-power Raman and EDFA optical amplifiers Safety practices during installation and restoration Potential safety problems, including causes and possible solutions Safety in confined spaces Types of personal protective equipment.Bonus materials include a student quiz with matching instructor version, written in Microsoft Word, which enables customization for specific safety needs.BICSI recognizes Fiber Optic Safety DVD training for the following BICSI Continuing Education Credits (CECs): one RCDD; one RITP; one Installer 2, Copper/Fiber; one Technician, and one Certified Trainer.
EMAXX Telecom taps BTI Systems for 4G/WiMAX mobile backhaul, Ethernet business services
Metro optical transport systems company BTI Systems says that it has supplied packet-optical transport gear to EMAXX Telecom of Cambodia. Starting in the capital of Phnom Penh, EMAXX will use the equipment to become the first provider in Cambodia to offer 4G/WiMAX services, mobile backhaul services, IPLC/DPLC connections, and Ethernet business line services, over a 10-Gbps metro Ethernet ring, BTI asserts.“Our mission is to provide a national, high-quality, 4G communications network service for Internet and multimedia applications, including commerce, entertainment, and education for the development of Cambodia,” said Sean Ngu, CEO of EMAXX Telecom. “We required a single, unified platform to support our entire services offering and meet our transport requirements for mobile backhaul and high-performance Ethernet business line services. With BTI, we chose solutions that are cost-effective, scalable, reliable, provide low latency, and are MEF [Metro Ethernet Forum] certified, enabling us to compete aggressively.”EMAXX has deployed the modular BTI 7000 Series packet optical networking system as well as the BTI 700 Series, an MEF-certified platform that support the provision of such Ethernet services as E-LINE and E-LAN. The company’s proNX Service Management Suite enables services configuration.“Cambodia is a fast-growing and developing market with surging demand by consumers and businesses for mobile access to content such as video and other OTT services, as well as Ethernet business services,” said Marc Olivier, Vice President of Business Development, Asia Pacific at BTI Systems. “EMAXX is Cambodia’s first 10G metroE and they plan to expand rapidly beyond Phnom Penh to country-wide deployment. We look forward to working with them as they successfully add new subscribers and businesses and increase revenues.”
Multilayer restoration and service provisioning demonstrated in IST ONE trial
ADVA Optical Networking and its collaborators in the IST ONE project have successfully demonstrated automated multi-layer service provisioning and restoration in a network in northern Germany operated by Telefonica. The demonstration points the way towards significant opex and capex savings via close interworking between IP/MPLS and optical layers, say project participants.IST ONE, funded by the European Union, aims to provide a mechanism to promote multilayer network management in multivendor environments. In addition to ADVA Optical Networking and Telefonica, project members include Technische Universitat Braunschweig in Germany as coordinator, Universitat Politechnica de Catalunya in Spain, and Seoul National University in Korea.In the trial, algorithms developed by the program members enabled multilayer interaction between ADVA FSP 3000 ROADMs with the company’s RAYcontrol GMPLS control plane software and GMPLS UNI and Juniper Networks MX Series 3D Universal Edge Routers running MPLS. Jim Theodoras, senior director of technical marketing at ADVA Optical Networking, says the ROADMs acted as slaves to the edge routers for both restoration and service provision.The demonstration highlighted several performance and cost benefits of multilayer networking, Theodoras adds. For example, service restoration by switching to a spare wavelength is well understood. However, once switched to a protection path, traffic on the network can be vulnerable to problems on that path. The IST ONE trial demonstrated the ability to rapidly provision a backup for the protection path. As a result, carriers could delay a truck roll to fix the broken path if desirable; they also could initially provision fewer restoration paths, Theodoras explains.The resultant savings can be significant. Telefonica believes the multilayer restoration approach demonstrated in the trial can lead to a greater than 37% reduction in capital expenditures in IP/DWDM networks. Meanwhile, mean time to repair can be extended by a factor of 20 while maintaining 99.999% availability.Rapid service turn up also can benefit carriers by decreasing time to revenue as well as enabling service providers to meet rapidly evolving customer needs. Telefonica reports that it was able to turn up new services in less than 50 seconds. Carrier sales people find this feature particularly appealing, Theodoras says.“This trial really showcases the potential of new multi-layer networks,” said Juan Fernandez-Palacios, head of core network evolution at Telefonica I+D – Global CTO Unit, via a press release that trumpeted the trial’s results. “The level of simplicity and automation that we were able to achieve was incredible. We now have the opportunity to activate new services in seconds; previously this could take hours. What's more, we're also able to verify the drastic reduction in opex and capex that such a streamlined multi-layer setup will deliver in our network. This trial provides a clear understanding of what tomorrow's networks will look like.”ADVA Optical Networking and Juniper plan to take the features demonstrated in the trial to market. Theodoras says that at least three customers already have deployed a form of multilayer networking using ADVA and Juniper gear, but not to the level in the trial. These customers likely will see ONE-like capabilities in future service packs. Meanwhile, the companies plan to demonstrate the advanced feature set to other prospective customers.
